I love Arwen too. I definitely dont feel like its too lord of the rings. When i hear the name, the first thing I think of is how beautiful and classy it sounds, not the lord of the rings connection. I think Winnie is adorable, though I prefer the name Gwyneth as a first name. I love the suggestion of Winter. Its so fresh and spunky. I also adore the nn Minnie. Not sure if you'd like it or not, just an idea.
Good luck, I hope you find the perfect name.Welcome to nameberry!

Thanks, rhiatayler. Been lurking a while and decided it was time to jump in. Minnie is a great Aunt's name but does have all the same stuff going on as Winnie.
I'm glad you feel that way about Arwen! I would love to be able to use it and my husband is convinced the LoTR associations are forgotten. Still not sure though...
